State Highway 79 Bridge at the Red River

The State Highway 79 Bridge at the Red River was a bridge carrying Texas State Highway 79 and Oklahoma State Highway 79 over the Red River at the Texas-Oklahoma state line. The camelback pony truss bridge was 2255 ft long and had 21 truss spans. The Texas and Oklahoma highway departments built the bridge as a combined project in 1939. The bridge provided a direct route between Waurika, Oklahoma and Byers and Wichita Falls in Texas. The bridge was the only camelback pony truss bridge remaining on a Texas state highway and the fourth-longest truss bridge in the Texas state highway system prior to being demolished.

The bridge was added to the National Register of Historic Places on December 20, 1996.

In 2018, a new bridge was built at the location of the old bridge before the old bridge was demolished.
